Key facts

Movement disorders at a glance.

The essentials, in plain English - what the term covers, how it's assessed, and how it's treated in the UK today.

  • What it is

    An umbrella term for conditions that cause too little movement (hypokinetic) or too much unwanted movement (hyperkinetic).

  • Hypokinetic

    Parkinson's disease and other parkinsonian syndromes, including multiple system atrophy - slowness, stiffness and reduced movement.

  • Hyperkinetic

    Tremor, dystonia, chorea, myoclonus, tics and restless legs syndrome - extra, involuntary movement.

  • Key tool

    A detailed neurological history and examination remains the single most useful diagnostic step.

  • Imaging

    MRI brain excludes structural causes; DaTscan helps distinguish true parkinsonism from tremor mimics.

  • Management

    Condition-specific medication, botulinum toxin, physiotherapy and, for refractory cases, deep brain stimulation.

Why this guide matters

The pattern of movement tells the story.

Movement disorders span dozens of conditions, but three principles run through nearly all of them and shape how this guide is organised.

  • Examination beats a single test

    How a tremor or posture behaves - at rest, on action, on approach to a target - narrows the diagnosis before any scan is ordered.

  • Hypokinetic and hyperkinetic differ

    Too little movement (parkinsonism) and too much movement (chorea, dystonia, tics) need different assessment routes and different drugs.

  • A specialist clinic changes outcomes

    Movement disorder neurologists refine diagnosis, adjust medication over time and know when to consider surgery.

How the diagnosis is made

From an unusual movement to a clear plan.

The steps a UK neurologist will normally follow, in order - so you know what to expect and why.

  1. 01

    Assessing

    Detailed history

    Onset, progression, triggers, family history and medication review - many movement disorders are identified from the story alone.

  2. 02

    Assessing

    Neurological examination

    Watching the movement itself - resting versus action tremor, rigidity, bradykinesia, posture and gait - to classify the pattern.

  3. 03

    Assessing

    Distinguishing features review

    Asymmetry, response to distraction, associated autonomic or cerebellar signs help separate look-alike conditions.

  4. 04

    Confirming

    MRI brain

    Excludes structural causes - stroke, tumour or hydrocephalus - that can mimic a primary movement disorder.

  5. 05

    Confirming

    Specialist movement disorder clinic

    A neurologist with specific movement disorder training refines the diagnosis and plans treatment.

  6. 06

    Refining

    DaTscan where relevant

    For uncertain parkinsonism, a DaTscan checks dopamine transporter activity and helps confirm or exclude Parkinsonian syndromes.

  7. 07

    Refining

    Selective genetic testing

    Considered for young-onset disease, a strong family history or specific clinical patterns - not a routine first-line test.

Typical timeline: a first neurology visit to a settled plan over weeks to a few months.

Symptoms

What movement disorders actually look like.

The full spectrum, from resting tremor to abnormal posture. And the features that mean it's time to escalate.

  • Resting tremor

    Tremor present at rest and easing with movement - the classic Parkinsonian pattern, often starting in one hand.

  • Action and postural tremor

    Tremor that appears during voluntary movement or when holding a posture - typical of essential tremor.

  • Intention tremor

    Tremor that worsens as a limb approaches its target - usually points to a cerebellar cause.

  • Rigidity

    Increased resistance through the range of passive movement - a core feature of parkinsonian syndromes.

  • Bradykinesia

    Slowness and reduced amplitude of repeated movement - often the most disabling early symptom.

  • Involuntary movements

    Chorea, myoclonus and tics - sudden, irregular or jerky movements that vary widely in cause and severity.

  • Abnormal postures

    Sustained or repetitive twisting postures - the hallmark of dystonia, which can affect one region or the whole body.

  • Red flag - rapid progression

    Fast deterioration, early falls or poor levodopa response should prompt urgent specialist review for atypical parkinsonism.

Treatment

How movement disorders are treated in the UK.

Condition-specific medication first, botulinum toxin and therapy alongside it, and deep brain stimulation for refractory disease.

  • Levodopa

    The most effective symptomatic treatment for Parkinsonian syndromes - improves bradykinesia and rigidity, usually combined with a decarboxylase inhibitor.

  • Dopamine agonists

    An alternative or add-on to levodopa, particularly in younger patients - watch for impulse-control side effects.

  • Botulinum toxin

    First-line for focal and segmental dystonia - injections weaken overactive muscles and are repeated every few months.

  • Beta-blockers

    Propranolol is a standard first-line drug treatment for essential tremor, particularly when tremor affects daily tasks.

  • Primidone

    An anticonvulsant used as an alternative or add-on for essential tremor when beta-blockers are unsuitable or insufficient.

  • Deep brain stimulation

    Considered for refractory tremor, dystonia or advanced Parkinsonian syndromes once medication alone no longer gives good control.

  • Physiotherapy and OT

    Gait training, balance work and adaptive strategies help maintain independence and reduce fall risk across most movement disorders.

  • Specialist MDT input

    Commissioned neurology multidisciplinary teams coordinate medication, therapy, psychology and surgical referral where needed.

Red flags

When a movement disorder needs urgent attention.

Most movement disorders progress slowly and are managed in outpatient clinics. These are the situations that aren't - and where urgent review is needed.

  • Rapid progression

    Symptoms worsening over weeks rather than years raise concern for an atypical or secondary cause and need prompt review.

  • Early falls

    Falls within the first year of parkinsonism are unusual for typical Parkinson’s disease and suggest multiple system atrophy or a related syndrome.

  • Poor levodopa response

    Little or no improvement on an adequate trial of levodopa should prompt reassessment of the diagnosis.

  • Early autonomic failure

    Significant early bladder problems, blood pressure drops on standing, or erectile dysfunction point towards multiple system atrophy.

  • Early dementia or hallucinations

    Cognitive decline or visual hallucinations appearing early in the disease course need specialist assessment.

  • Sudden severe involuntary movements

    Acute onset chorea or ballism can reflect stroke, metabolic derangement or an autoimmune process and needs urgent assessment.

  • Status dystonicus

    Severe, continuous dystonic spasms are a medical emergency that can cause rhabdomyolysis and respiratory compromise.

  • Drug-induced movement disorder

    New tremor, dystonia or dyskinesia after starting antipsychotics or antiemetics warrants a medication review.

  • Functional overlay

    Inconsistent or distractible movements deserve a compassionate specialist opinion rather than dismissal.

Living with it

A long-term condition, with a clear support plan.

Four things that make the biggest difference day to day - staying active, allowing time for medication to be tuned, using therapy fully and asking about specialist options early.

A quiet reminder

Small daily habits protect function over years.

Regular exercise and consistent medication timing do more for long-term independence than any single intervention.

  1. 01 Routine

    Build movement into the day

    Regular, structured exercise - including balance and strength work - helps maintain function across most movement disorders.

  2. 02 Patience

    Medication takes fine-tuning

    Doses and timing are often adjusted over months to balance symptom control against side effects.

  3. 03 Support

    Therapy is not an afterthought

    Physiotherapy, occupational therapy and speech and language therapy meaningfully improve day-to-day independence.

  4. 04 Escalate

    Ask about specialist options early

    If symptoms are poorly controlled, ask about deep brain stimulation or specialist MDT review rather than waiting.

Frequently asked

Everything we get asked about movement disorders.

Quick answers on diagnosis, DaTscans, tremor types and treatment options.

  • What exactly is a movement disorder?

    A broad group of neurological conditions that affect the speed, quality or control of voluntary movement. They are split into hypokinetic disorders, which cause slowness and reduced movement, and hyperkinetic disorders, which cause extra, involuntary movement.

  • How is a movement disorder diagnosed?

    Mainly through a detailed history and neurological examination, since the pattern and character of the movement often points directly to the diagnosis. MRI brain excludes structural causes, and a DaTscan can help confirm parkinsonism when the picture is unclear.

  • What is the difference between Parkinson’s disease and essential tremor?

    Parkinson’s disease typically causes a resting tremor along with rigidity and bradykinesia, and usually starts on one side. Essential tremor is an action tremor that appears during movement or posture-holding, without the rigidity or slowness seen in Parkinson’s.

  • What is a DaTscan and when is it used?

    A DaTscan is a nuclear medicine scan that measures dopamine transporter activity in the brain. It is used when the clinical picture is uncertain, to help distinguish true parkinsonism from conditions such as essential tremor that can look similar.

  • Can movement disorders be cured?

    Most cannot be cured, but symptoms can usually be well controlled with medication, botulinum toxin or therapy. For some patients with refractory tremor, dystonia or advanced Parkinsonian syndromes, deep brain stimulation offers significant and lasting improvement.

  • When should I see a specialist about tremor or unusual movements?

    If a movement is new, progressive, affecting daily tasks, or accompanied by falls, cognitive change or autonomic symptoms, ask your GP for referral to a specialist movement disorder clinic rather than waiting to see if it settles.
